REFLECTION AND STRETCHES

Hey guys!! I'm Macy and I sit at the table in front of the class with my 4 other "friends". First off, I hope we all did well on the quiz we did yesterday. We also learned 2 new topics yesterday, REFLECTION and STRETCHES!

REFLECTION

STRETCHES

• has 2 types: Vertical and Horizontal stretches

1. Vertical Stretches

          -  the stretching of the graph away from the x-axis.
        - if the original (parent) function is y = f (x), the vertical stretching or compressing of           the function is the function a f(x).

• if 0 < a < 1 (a fraction), the graph iscompressed vertically by a factor
  of a units.
• if a > 1, the graph is stretched vertically by a factor of a units.

  

2. Horizontal Stretches

        - the stretching of the graph away from the y-axis. 

- if the original (parent) function is y = f (x), the horizontal stretching or            compressing of the function is the function f (ax).

if 0 < a < 1 (a fraction), the graph isstretched horizontally by a factor of a units.

if a > 1, the graph is compressed horizontally by a factor of a units. Here is a link that will help you understand REFLECTIONS and STRETCHES more:  Transformations Summary: Stretches, Reflections, Translations I hope I helped you understand more how to deal with Reflections and Stretches. If I wasn't able to help then I suggest you to ask Mr. Piatek. :) Oh and since we're all great mathematicians.. Here's a (lame) math joke to end my blog post: Q: What is the definition of a polar bear? A: A rectangular bear after a coordinate transformation.
